Thanks.
Of course. I see now the lack of recharge-ability ( rechargeableness ? :)) is the downside.
I am making a one off installation that just needs to last 10 days. I assume that as they are single use I can run them all the way down and get nearly the whole capacity out of them without worrying about damaging the disposable battery.
This makes the pricing seem favourable again, and also being 9v I don't have to worry about overheating the arduino, and therefore dont have to get a stepping regulator.
I have managed to find out that an average electric fence uses about 60 milliamps of current, so do you think these Batts will manage outputting a continuous current between 90 and 200 milliamps ?
Many Thanks
